I ARSIENEl IZEPZIEEIN, BROKLNE; -MASSCHUSETT snoexnnsonsnn.

To all whomz't may concern.:- ZEPPELIN, a citizen of the United States, and a resident of Brookline, county of Norfolk, and` State of Massachusetts, (whose post-office address is Davis avenue, Brookline, Massachustts,) have invented an Improvement in. Shock-Absorbers, of which the :following:de-` scription, in connection with the' accompanying drawings, is aspeciiication, like char` acters on the drawings.representing like.

parts.-^

My invention relates to shoelr absorbers for vehicles, and -aims to provide an improved device of this character `which will be an im'provement upon and 'muchless expensive to construct than similar devices nowv in use for that purpose, and which will be also a satisfactory vsubstitute for the lpneumatic tires as well, now so generally used.

In the drawings, Figure 1 is a front elevation of my improved shock absorber, Fig. 21s a plan thereof, partly 1n section, Fig. 3,'

a vertical cross ,section on theline 3-3, Fig. 1, viewed .from'the right, and Fig. 4,'a ver-` tical cross section on the line 4 4, Fig. 1, viewed from the right.

Referring to Fig. 1, my improved shock absorber is shown as comprising` cushion members, and supports therefor, so disposed as to act angularly relative to each other 'and positioned between the axle and the vehicle body, andherein comprises, tirst, supports 1, each in .the form of a clip or .clamp comprising an upper member 2 and an opposed and cooperating lower locking member 3 adapted to be secured in any suitable manner, as by bolts and nuts 4;, lto an axle 5. These. clamping members 2 and 3 vmaybe fashioned to permit them to engage and spring seaft carryin1 member, as av bellcrank lever .7; the upri ta'rm of which is shown'` las and 'preferably 'is' shorter' than the i securedto the lower end of said. lever as by' l llaterally extended arm. A spring carrying vehicle :uipporting block or seat 8 1s movably `speueauou of Letters-raient Application nea november 17,*1911. serial no. 660,379.

the pin 9V is a cushioning device shown here# 1n as a link, 10, extendedthrough anaperture 11 in a spring supporting plate or seat 12 on the'xnember 3, and which acts as a seat for a spring 13, coiled about the lowerporvtion of said link 10 and interposed'between said seat 1-2 and the opposed seat andnut 14.5 on the end 'of said link. The 'upper end, see Fig. 2, of each lever 7 is yieldinglyponnected with the corresponding end of a Similar lever `similarly positioned relative to the axle at Aor .near the opposite end thereof and is shown herein as pivotally secured thereto, preferably by a plurality of links 15. One end of each link 15 is herein .threaded to receive thereon a turn-buckle '16, by means of which said. link is adjustably secured to a piston- 17 in a spring barrel 1S. preferably positioned above and substantially parallel with the axle.

Within the bar-rel 1.8, Fig. 2. each-piston 17 hascoiled about ita spring 19, which is interposed between a nut.- or plate 2O on Athe end-of said piston a cap or head 21of said barrel -forming 'seats :forsaid spring. The plates 20 may be positioned .within said barrel side by side, and abutting; one against the other, or jl may, and preferably do, interpose betweensaid plates a cushion lmember or device asa spring 22, which serves tofreiniiorce the two springs 19 and springs. B v 'the use of this springA 22 the springs 19 may be retained. under less compression Within the barrel. and such an ar rangementresults-in a more sensitire -and delicate adjustment of said springs, which also causes them to respond more readily `to any.. unevenness xn the road than they would otherwise do.. The body` being 'mounted en springs secured in turn to the seat-s 81bvv1ll be obvious that the car body will be' suspended by the springs 19, said Patented Sept. 3, 1912.

lalso acts as a cushion. member between .said

springs acting. as vcushion membersto take up any vshock that tends to lower the car, and also to'limitsuch movement of the car, and in conneotionwith the springs 13 and spring 22, act as cushionlmembers to take upLany shock tending to raise the vehicle body, and alsoto limitsuch movement.

be applied to Aeither the ront or rear axle'of sive v.to construct.. Doubtless modifications .los The above described lshock absorber mayv fa vehicle with equal facility, is simple in l arrangement I and comparatively -mexpemf of said levers -in a lateral direction.

2. Shock absorbing means for vehicles comprising a plurality of lever supports adapted to be secured to the axle, bell crank levers mounted in said supports, a spring seat on each of-said supports, a spring carrying link depending from the longer lateral arm of each lever, a spring on said link seated against said spring seat a vehicle carrying seat carried by each lever, links secured to the short-er of said lever arms, oppositely disposed spring seats carried by said links, springs seated theree.

on in substantial relative alinement, a'

spring barrel for said springs constituting seats for the springs, a reinforcing spring interposed between Said first-named springs, whereby downward movement of the vehicle causes lateral movement of saidV springs, and lateral movement of said shorterflever arms to a less degree thanthe `movement of said first-named lever arms.

3. 'Shock absorbing means for. vehicles comprising axle clips, bell crank levers pivotally mounted on said clips, spring members connected with said levers to control the upward movement thereof, and a plu-A ralityof resilient members operatively connected 'and positioned end-Wise l relatively to each other 'and substantially parallel to the axle to control the lateral motion yof said levers.

.4. Shock absorbing means for vehicles, comprising an axle, clips thereon, levers mounted in'said clips, vehicle -spring seats ,on said levers and' springs arranged to yield at substantially right angles to each other to control the movements of said spring seats.

5. Shock absorbing means for vehicles comprising clips, levers mounted thereon, springs adapted to regulate the movement 4oi' said levers in one direction and oppositely acting springs mounted in a spring case suspended between and connecting said levers and adapted to regulate thel movenient of said. levers in adirection angular to said iirst named direction.

G. Shock absorbing means forvehieles comprising lever supports adaptedA to be secured to the axle, levers, the two arms of which are of unequal length, mounted therey on, lvehicle carrying members carried b v Said levers, springs for controlling the movement of said levers in one direct-ion and a plurality of bodily movable springs connecting said levers.

7. Shock absorbing `means for vehicles comprising lever supports adapted to be secured to the axle, vehicle carrying levers thereon, upright spring members on said supports connected to said levers and acting to cushion the movement of one arm of said levers in a direction substantially parallel with the axle, and opposed spring members connecting, and acting to cushion the movement yof one arm of each of said levers in a substantially vertical direction.

In testimony whereof, I have signed my name to this specification, in theY presence of two subscribing witnesses.
